1. The problem is to identify the coordinates of point $A$ given as $(-10, 10)$. 2. Coordinates are written as $(x, y)$ where $x$ is the horizontal position and $y$ is the vertical position on the Cartesian plane. 3. Here, $x = -10$ means point $A$ is 10 units to the left of the origin (0,0). 4. $y = 10$ means point $A$ is 10 units above the origin. 5. So, point $A$ is located 10 units left and 10 units up from the origin on the Cartesian coordinate system.
